My Problem is more General and maybe has nothing to to with an global_ID:
I have worked with Survey123 and have takken photos to spezific objects. I've exported those photos via "https://community.esri.com/groups/survey123/blog/2017/03/22/working-with-your-survey123-photos" to work with them via attachments. Now i want to intersect the Information and photos of an object, wich i've recorded via survey123, with already existing informations of this object. The Primary-Key between these two feature-Clases is the adress.
By intersecting these two classes, there's no problem for all attributes but the photos. because with the new Intersection-class i've none relation to the Attachments of the photos. So i basically need a way to access the pictures after intersecting the two classes...
Finally i want to display all informations and Pictures of the objects via map series in ArcGIS-Pro via dynamic text and dynamic Pictures. If there would be an Option to display dynamic text and photos from more than just one feature-class, there would be no problem. Cause then i would display the text from the one and the photos from the other corresponding feature-class. But i think it's not possible.
Perhaps the problem is now somewhat clearer.
